Sayid says that the woman responsible for her (he doesn't say Shannon's name) death thought she was someone else. "Someone coming to hurt her. Someone like you!" Henry's like, "Oh shit." He tries telling Sayid that hurting him isn't going to bring her back. But Sayid seems to have an alternative theory: that it will. And he starts pounding on Henry, standing up over him, demanding Henry tell him who he really is, and it turns out that Henry's real name is "Help Me."
Outside the door, we hear the muffled thuds and Henry's cries. Jack goes over to the door. "Sayid! Sayid! Have you seen my pliers? I really need them!" He tells Locke to open the damn door, but Locke says, "Jack, this has to happen." Yeah? Well, now this is happening. Jack grabs Locke and throws him against a wall. That's just how Jack rolls. "Open that damn door, you understand me? You open it now!" Again, Locke says no. And then, the familiar beeping of the science vs. faith timer starts. Advantage: Jack.
Inside the armoury, the beating continues. Henry says whatever Sayid wants him to do, he'll do it. Sayid says he wants the truth, and for the first time since 1992, the answer is not, "You can't handle the truth!"
Locke wants Jack to let him go so he can enter the numbers for the timer, but Jack won't let him until he agrees to open the door. "It's under a minute now, John. You better think fast." Locke can't believe Jack would risk everyone's lives, but Jack's through with the button, apparently. "You talked me into pushing that button once, John, but it's yours now. You're the one who won't risk it. You. Me? I don't think anything's going to happen when we get down to zero." Matthew Fox is doing his best Crazy Face here as he plays chicken with Locke. Locke tries giving him the combination. "You think I'm stupid? You open it," says Jack, and he shoves Locke towards the door. Locke quickly enters the combination, then runs for the computer room.
The timer has hit ten seconds, and the beeping speeds up. He starts typing the numbers. Meanwhile, Jack hauls a rabid Sayid out of the armoury. Locke, however, has to backspace, having entered 16 twice in his haste. But the timer hits zero; the beeping stops, and the numbers start spinning; instead of white numbers, the spaces where the minutes were displayed are black and where the seconds were, the spaces are red. Then, one by one, they start settling on what look like Egyptian hieroglyphs: a bird, a dart, a flame or something, a little squiggle...there's still one spinning around. Locke's been momentarily stunned by this new development, but he quickly finishes entering the numbers and hits "execute." The timer resets to its customary 108 minutes, and Locke's really relieved. He'd seen last week's previews as well, and was under the impression we'd find out what happens when the timer runs out. But it looks like we're still on schedule to find out what happens sometime around Season 5.
